Embodiment 1

[0019] A kind of production method of imitation leather fabric described in the present embodiment, comprises the steps:

[0020] (1) Steps of selecting and coiling the base fabric;

[0021] (2) The step of uniformly coating the resin material on the base cloth;

[0022] (3) The step of solidifying the resin material;

[0023] (4) Steps of squeezing and washing;

[0024] (5) A step of uniformly coating the prepared polyurethane slurry on the coated release paper; wherein the polyurethane slurry contains butanone and N-methylethanolamine. Other components in the polyurethane slurry are selected from the prior art.

[0025] (6) The step of attaching the coated release paper to the above-mentioned base cloth and completely drying the release paper again;

[0026] (7) The step of separating the release paper.

[0027] A kind of production method of imitation leather fabric described in this embodiment, it is mainly divided into seven major steps, compact and reasonable, can e...

Embodiment 2

[0029] The production method of a kind of imitation leather fabric described in this embodiment is different from Embodiment 1 in that: (1), the step of selecting and winding the base cloth;

[0030] (2) The step of uniformly coating the resin material on the base cloth;

[0031] (3) The step of solidifying the resin material;

[0032] (4) Steps of squeezing and washing;

[0033] (5) A step of uniformly coating the prepared polyurethane slurry on the coated release paper; wherein the polyurethane slurry contains butanone and N-methylethanolamine. Specifically: the polyurethane slurry is composed as follows in parts by mass: 100 parts of polyurethane, 5 parts of dimethylamide, 20 parts of butanone, 15 parts of deionized water, 1 part of N-methylethanolamine , 1 part of sodium butylene dioic acid diisoester octane sulfonate, 5 parts of dye paste;

[0034] (6) The step of attaching the coated release paper to the above-mentioned base cloth and completely drying the release pap...

Embodiment 3

[0039] The production method of a leather-like fabric described in this embodiment is different from Example 1 in that: the base fabric is made of microfiber cloth, which can further improve the comfort of the leather-like fabric.

Abstract

The invention discloses an imitation leather fabric production method. The imitation leather fabric production method includes the following steps that first, base fabric is selected and reeled up; second, the base fabric is evenly coated with resin material; third, the resin material is solidified; fourth, extrusion and water washing are performed; fifth, coating release paper is evenly coated with prepared polyurethane slurry, wherein the polyurethane slurry contains butanone and N-methyl ethanolamine; sixth, the coating release paper is attached to the base fabric and totally dried again; seventh, the release paper is separated. The imitation leather fabric production method is compact, reasonable and capable of effectively improving production efficiency; the coating fabric formed through the polyurethane slurry is even in micropore and not prone to expansion with water; besides, free coloring can be performed, physical indexes such as color fastness, illuminance, peel strength and tear strength can be freely adjusted, and thus the produced imitation leather fabric can be more excellent in performance.

Description

technical field [0001] The invention relates to a production method of a fabric, in particular to a production method of an imitation leather fabric. Background technique [0002] With the development of society, people have higher and higher requirements for life, especially for fabrics. Real leather is highly recognized by consumers for its comfortable performance, but its price is relatively high, and ordinary people cannot afford or wear it. Therefore imitation leather fabric arises at the historic moment. [0003] The imitation leather fabric is made of synthetic materials, it is not afraid of moth, not easy to mold, and the surface has good water resistance, but synthetic leather is not resistant to high temperature and chemical substances. There are many kinds of imitation leather fabrics such as PU and PVC. PU leather: PU is polyurethane, which is divided into polyether type and polypolyester type, and PU leather refers to a kind of artificial leather product of...
